Changed cam tensioners at 53,500. Seems likeI have a vibration at approximately 30-50 mph. Sled seemsto run fineotherwise.Typical cruising speed of 78-80 everything feels normal.Starts easily, gas mileage is very close if not the same as before. Haven't ridden it much since changing tensioners due to weather and a concern of doing damage.Was wondering if counter balances might be 180* out. Not sure if that's possible being I didn't remove any of that assembly. Thanks in advance for any and all help/comments.
